To estimate the power flow transmission from the vibrating internal combustion engines to the complex elastic foundation accurately, a general analytical model is presented by extending the classical one. In the proposed model, the Mindlin plate, instead of the classical thin plate based on Kirchihoff's hypothesis, is used to model the elastic isolation foundations. Substructure technique and variational principle are employed to derive the governing equation and solve the power flow transmitted into the thick or orthotropic beam foundations with different configurations. Comparative study on the transmission characteristics of the power flow of the general isolation systems with the classical cases is conducted. Numerical simulation shows that the presented model is valid and it can obtain more accurate power flow solutions than the classical one.
